Switched on the computer this morning and for the umpteenth time come month end AVG has done an update and the computer is jammed, it won't connect to wifi or ethernet, it seems to be stuck in a loop trying to install AVG. Why? Why does AVG do this with monotonous regularity, we need the computers to work, we cannot have the computer down for hours at month end. And getting hold of support is frightful.
